My white Preferred model listed at $28,845. Dealer had it listed on their website for $1,317 less, at $27,529. Also got the $750 Mazda loyalty discount (we currently have four Mazdas from same dealer). Total at $26,778...
I got about the same price on a Soul Red Preferred near Pittsburgh. I believe I said this in a previous thread - go to KBB or similar site to get the
invoice price of the model you want. Ignore the MSRP. Dealers are taking offers at, and sometimes below, invoice. Use that as a guide. Although it will depend on inventory and geography, most people should easily be able to offer invoice price and get the car with minimal negotiation.
Second tip, if you know you want the CX-30 and are just shopping for the best deal, don't go in to the dealer and get stuck with a floor salesperson (tag-teaming with their manager). Contact the dealer via their website for the web salesperson and get an offer or negotiate a price via email or phone. The web sales team knows you are shopping around and knows that you know the invoice price. They are going to give you an aggressive offer to get you into the dealership.
Third tip, as I just said above, ask for a quote of the total taxable amount because that will include all dealer fees. That way they know that if they slip in any extra fees, they will only raise their price relative to their competition. And it lets you know that you are comparing apples to apples when you shop multiple dealers.
Final tip - use a service like True Car or KBB to contact local dealers for you and invite them to give you a quote. (You will have to let the service share your email and phone number with the dealers. I use a burner email address and phone for car shopping so they don't get my "real" contact info.) That way the dealers know that they are in a bidding war and will have to work hard for your business. And it dove tails with the second tip, and keeps you out of the dealership until you are ready to sign papers.
